[Rails] how to update rails 2 to rails 3

Hi,

I m new to rails. I have funny things when trying to change version of
rails.
I have installed ruby 1.6.5.1 and ruby 1.9.3. I installed RVM and
everything correctly.

When i change ruby version with rvm use 1.9.3 it succesfully change
ruby, when type
ruby -v it shows 1.9.3 .

But then I try to install rails 3 with rvm gem install rails, it shows
rails 3.2.6 is sucesfully installed but when I type rails -v it shows
2.8.6 again.

When i type gem rails list it shows that 2.8.6 and 3.2.6 are installed,
but how can I make terminal
shows 3.2.6 when I run rails -v command?

Also how can I use jruby 1.6.5.1 as ruby 1.9?
And how to create sucesfully new project specifzing version for example>

rails _3.2.6_ new test

When I try it shows me errors.

Thanks in advance
